Length tool compensation and tool diameter compensation

Hi there i am new to the comunity i am running a cnc router and a cnc milling at my job and i ordered a altmill a couple of month ago will receive it soon i have been wondering can you correct the lenght of a tool in g sender so you can lift up a chanfer bit to lower it slowly to ajust your chanfer height and can you run whit a cutter diametter compensation so you can fine tune a diameter hole or joinery

Hi Doum,

I believe the functions you like to see (if I even understand your quiry correctly) are not ative to gsender. When gsender runs a toolpath the only variables to be tamper with are feed of the machine and rpm of the spindle. Z-height is set before starting the program and after starting the machine, controled by the toolpath, no longer listening to outside user inputs. Tool diameter is determined by the Design software tool library and the tool you chose to use. However, there are a few ways to be able to play around with tollerances to be able to creap up to a trial and error fitting.

In gsender you can always use a conservative z-zero and run a champfer tooltpath to see if the result is of you liking. You can either let the programm run its course or stop it and reset your z-zero a wee lower and restart untill you get the desired result.

I like do these creep actions on the design side of the process and create the toolpaths with clear indication of how much creep is in the toolpath so I can load the desired offset directly into gsender the next time I run the same project.

The first time it’s a wee more hussle than tamperingmwith setting in gsender, but when the toolpaths are available, it’s load and run, stop, load and run untill the right toolpath is found.

So the direct answer to your question is no, but indirectly, I’d say yes.

Disclai er, this is all to my novice knowledge. I’m sure if there are options in gsender to do your biddings, someone will jump in and call them out.

And.. if it’s something you need or would like to see implemented in gsender, you can allways suggest this in a suggestion towards the devs. Who knows, your creep up funvtion resonates with more users.

Thanks for the answer i was just wondering cause this is some nice feature that i like working whit make life more easier

Hi Doum,

You casn post a suggestion for your function in this here section/ Who knows it might be implemented. Using workarounds using design software will still be needed, for implementing such features in gsender might take a while if ever.

FE: to sneak up on a fitting outine, I change the specs for a bit in toolpaths to being smaller bit than it actually is. This gives you the power to exactly create a slightly wider outline. Most design software do give the option to include an offset to the toolpath, that does pretty much the same with less calculation (I always get wrong.)

A suggestion topic can be created here:

If you have questions on howto workaround the limitations of gsender, just lay out the problem and I’m sure someone has encountered said problem, delth with it and came up with a solution, and is willing to share.

@Doum87 I have deleted your duplicate post on this issue. There is no need to repeat your question. If you have something to add to your original question, you can edit it.

I want to make a sugestion for a improvement this is why the double post

@Doum87 I apologize. Clearly, I did not read your other post carefully enough. By all means, if you have a suggestion, create a post in the suggestion category explaining what your suggest is.

When you’re talking about cutter length compensation for a chamfering bit, that should be able to be accomplished by tweaking your Z-zero until it carves the way you’re wanting it to

In regards to tool diameter compensation, this would need to be something implemented in our machine firmware first before gSender could do any work with it after the fact. This would be something we’d implement far down the road from now just because there are so many other features we feel we need to work on first

Does that address both your questions?
